Tina was a beautiful teenager; she had just turned 18 a week before and she was still living with her parents in an upmarket suburban part of her hometown. Tina’s Dad was a self-made millionaire businessman, and he ran a chain of successful restaurants around the country, so he was away on business quite a lot. Tina’s Mom was quite the socialite and enjoyed wine evenings at various friends’ houses during the week if she wasn’t off shopping. Tina had finished high school and was going to take a nice gap year to really decide what she wanted to study as she had no real idea what she wanted to do.

Tina stood 5ft 4” and was petite and fit, with beautiful bright blue eyes, long blonde hair and an athletic figure and a pert tight ass, she had 34A tits and nice toned legs. She took full advantage of the home gym they had and worked out daily. And if not, she jogged 3-5km every second day.

Tina was at home one late afternoon during the week, her mom was out with the girls having a wine tasting event so she would be home very late and probably drunk, Dad was roughly 300 miles away on business, so Tina decided what better way than to pop on her bikini turn on the stereo and lounge by the pool.

Rex their dog a, cross Great Dane and Ridgeback was her only companion, and he loved being around Tina as she was the one who would take him for a run when she jogged, and she fed and watered him daily. Tina loved him a lot, he was super goofy and didn’t understand his size and still thought he was a puppy. He was 3 years old and a really goofy dog and loved to play and run.

Rex curled up next to Tina on the patio where she was lounging enjoying the afternoon sun and reading a soppy romance novel, Tina knew they were corny, but the stories always turned her on a bit.

Tina suddenly thought, “Hey! I’m home alone, no one can see me! So, she stripped off her bikini and lay back on the pool lounger naked, this is perfect! I can get an even tan now no strap lines LOL, and it feels so liberating to be naked and free she thought, her nipples hardened, being naked and alone turned her on a lot, Tina loved being naked.

Reading her racy romance story had turned Tina on, she placed her book aside and reached up and cupped her tiny tits and pinched her nipples making her moan softly, biting her bottom lip in lust, continuing to massage her right breast and nipple, she ran her other hand down to her smooth hairless pussy and started rubbing her clit softly in circles.

Tina’s pussy flushed, dripping wet, she spread her legs and inserted one finger into her wet tight pussy and fingered herself, gently moaning in pleasure, teasing her hard nipples and small tits at the same time. Tina had only had sex once before with her ex-boyfriend and he was a drip and came in 2 minutes, also he had a small cock, then he cheated on her the week after, so she kicked his ass to the curb and had been happily single since. Rex smelled Tina’s arousal in the air and lifted his big head at the sounds of her moans as she pleasured herself, his cock twitched, female sex pheromones were strong in the air he needed to find the source.

Tina’s eyes were closed tight as she worked her tight teen pussy, finger fucking herself, moaning close to Cumming when she felt a hot breath on her bald pussy mound, a huge hot tongue lapped over her soaking wet clit hood, her eyes shot open glancing down, Rex had his huge head between her legs and had lapped at her wet juices OMG she gasped!

Rex !!! naughty boy!! Tina yelled sitting up, her cheeks flushed in embarrassment, OMG my dog had just licked my pussy! It felt so wrong and dirty but it kind of turned her on, her nipples were super hard and her tummy had butterflies, ummm, maybe I should see if he would lick me out, Tina thought, feeling dirty but it reminded her of one dirtier romance novels where a woman had sex with a werewolf.

Tina got up from the pool lounger and paced naked into the main lounge her head spinning, Rex following her closely, are you really going to let your dog eat your pussy Tina? she thought? In the lounge there was a large ottoman in the middle of the room that she could lie back on comfortably, if she was going to do this it was now or never, she thought, her heart was thumping hard in her chest, her nipples hard and her pussy dripping wet.

Fuck it I’m so God dam horny!!! Tina said out loud, Rex was sitting behind her his cock stiff he was panting loudly, he could smell her musk, you’re only licking me, Rex!! Tina said aloud and lay back on the ottoman spreading her legs open wide, come here Rex, good boy, she patted her pussy mound, Rex immediately darted between her open legs whimpering at Tina, basically asking her approval.

Yes, Rex eat my pussy!! Tina said loudly, she was so horny and couldn’t believe she was going to allow Rex to eat her pussy, Mom was going to be home very late so there was no risk of getting caught, Tina reached down and spread her tiny bald pussy lips, eat me, Rex!!

Rex didn’t need any more encouragement, he dove right in between Tina’s fit legs and started to lap his huge rough tongue over her asshole up over her flushed spread pussy lips and clit hood in one swift lapping motion, Tina threw her head back her lower back arching as Rex eagerly lapped at her tiny pussy, her hands fell to her sides, grabbing tight onto the upholstery, OMG. YESSSSSS mmmmm Rex!!! She came instantly her pussy juices flowed, dripping down her asshole and soaking the ottoman, Rex lapped her bald teen pussy hard and fast, her sweet juices making him super horny, Tina’s toes curled up, her legs open wide in hard orgasm her breath panting in ragged gasps, OMG Rex!!! YESSSSSS NNNNNN!!!!!! She came again her tummy spasmed in wave after wave of orgasm, she squirted over his snout which in Rex’s mind said this bitch needed mating, his hips started to hump as he licked Tina’s pussy with furious enjoyment.

Tina’s head slammed back again onto the ottoman her back arched as another massive orgasm tore through her body like a tidal wave, then slowly faded off leaving her legs shaking, panting Tina had never experienced such a powerful orgasm before. Rex now had other plans, his cock tip was out of its sheath, angry red and swelling, he needed to breed Tina, he climbed up onto the ottoman and placed his front paws next to Tina’s slender hips. Tina saw this happen and knew his intent, No Rex!! No!! just licking she said but Rex refused he was going to fuck Tina and give her his dog seed. Tina was weak from her massive orgasm, her legs still spread open wide, Rex moved forward and thrust his now massive red dog cock at her slick pussy.

Tina looked down at Rex now trying to hump her, his massive cock was now fully out of its sheath, red, thick and its huge knot swollen he was at least 8 inches long and at its thickest his cock was at least 6cm thick, she gasped, Tina swallowed hard but thought you can’t deny your pup who licked you to such amazing orgasms, deep inside her perverse mind remembered how turned on she got reading her book about the woman fucking the werewolf, now the thought of her fucking Rex really turned her on, I wonder if his cock will even fit in me she thought making her pussy even wetter.

Tina slid down off of the ottoman and rolled over onto her knees, her chest lying flat on the ottoman this gave Rex the perfect angle to penetrate Tina’s tight teen pussy. I’m going to let Rex fuck me, mmmmm she blushed hard, but her pussy flooded juices flowed some trailing down her inner thighs at the thought of her fucking her loyal dog. Rex was humping the air just above Tina’s tight bald pussy, she reached down and grabbed his huge red cock. It was veiny and as thick as a man’s wrist and very hot with blue veins throbbing and it’s tip spouting precum.

Tina made up her mind, she was so horny, she was going to let Rex fuck her tight 18-year-old teen pussy this evening, she guided his huge red member to her pussy opening then released his cock letting Rex take control.

Rex lunged forward guiding his huge red cock directly to her tight teen pussy hole, he thrust with vigor and passion, then his cock tip hit the mark, he thrust once more and drove his swollen cock tip into Tina’s tight cunt, Tina yelped out loud as Rex’s cock tip entered her tight teen pussy, then he rammed it home, balls deep stretching Tina’s pussy wide open, slamming his cock tip up past her belly button. Her tight teen pussy sucking onto his red doggie cock. Her tight pussy spasmed as it took his full girth, Tina grit her teeth and yelled out OMG Rex owww your cock is so thick and deep!!! Rex started to piston his cock deep into her tight wet pussy his big balls slapping her clit with every brutal thrust, loud fuck noises echoed throughout the lounge as Rex mated his teen bitch. His front paws locked tightly around her slender waist helping him ram his huge cock into Tina’s tight slick pussy.

With every deep thrust Rex’s cock blasted deep into Tina, his red cock stretching her pussy open wide his knot slamming against her pussy lips, his tip thrusting past her belly button touching her cervix, Rex fucked Tina hard and deep, she was panting and moaning loudly, Tina’s eyes rolled back as she felt another orgasm building, her toes curled and she pushed back against his hard thrusts, then in one huge pump Rex’s swollen knot pushed into her, Tina yelled out in pain and exploded in a massive orgasm seeing stars as Rex’s cock locked deep inside her now fully stuffed pussy and he started to cum in big hot spurts, Tina still orgasming could feel his cock filling her up with his hot doggy cum, spurt after spurt, not a drop would leak out as his huge fat knot was locked in tight, sealing his cock inside her teen pussy.

Rex stayed tied to Tina for at least 25 minutes before his knot shank enough to allow him to pull out of her now cum filled womb, with a loud PLOP his swollen cock pulled out of Tina, she squealed as he did so, some of his cum running down her thighs and splashing onto the floor. Tina lay on the ottoman panting, she had been continuously orgasming over his locked in cock, her legs trembled as her stretched out pussy leaked dog cum onto the floor. My God Rex that was amazing she panted, I have never felt such pleasure in my life! Good Boy Rex!!!

Rex went over to his doggy bed curled up and licked at his still swollen cum overed cock, licking his cum and Tina’s juices off it.

Tina let Rex fuck her one more time that night this time in the missionary position, Rex locked into her swollen pussy for 30 minutes, the sex was amazing! Tina had multiple orgasms over his huge cock, she had never felt such pleasure, she loved feeling his cock bulging in her tummy once he was locked inside her pussy with the huge knot stretching her lips and pumping her full of his doggy seed.

Tina’s mind was now completely made up that she was only ever going to fuck Rex from now on, boys were so egotistical and assholes, All Rex wanted was love and would give Tina his cock anytime she wanted it, Tina was now a fully-fledged dog sex nymphomaniac. Anytime she was home alone Tina would let Rex lick and fuck her as many time as he could before her mom came home, she was addicted to his huge dog cock, and she also regularly would blow him and swallow his delicious salty dog cum, draining the cum from his big balls on a weekly basis.
